Smartwitness cameras - NVS/Accessory camera not displaying
Possible Causes: No Video Signal events get generated whenever there is a loss of camera feed on any channel. It might be intermittent.
This might be due to the fact that there is a loose or pinched cable, lack of any accessory camera on the channel, or a faulty cable or camera.
Steps to be followed:
- Check the connection between the DVR and the accessory camera for any loose or pinched cables; check if the camera is operational by replacing it with a spare one;
- We need to confirm if it's a camera issue or a cable issue so that we can replace it accordingly.
1. Disconnect all secondary devices from the camera unit
2. Connect each camera one by one on CH1
- If all secondary cameras are working on CH1 the issue is most likely in the Camera input cable.
- If you have a spare Camera input cable, swap it out to test, in order to further isolate the issue and confirm that it is a problem with the cable.
3. If any of the cameras don't work when plugged into CH1 or the issue is isolated to a possible faulty Camera Input Cable, contact support and report the troubleshooting steps performed.
